Review: Easy to read; accurate; small; works well; looks good - Overall, this is a pretty decent item. I've only had it for 6 months now, but I really like it. It's especially nice because it's pretty accurate and costs ~$50-60 (wait for a deal) and I don't have to waste money going to get new sensors replaced for $100+ a TPMS sensor. Overall, it was worth the purchase as it's very convenient to see the current pressure/temperature for each wheel (if you don't have that with your vehicle already). This product works by replacing your cap for the air valve with a sensor and nut. Once the cap is off, you thread on the [locking] nut and then put on the sensor hand tight. You then "loosen" the nut which winds up using friction to keep the sensor tight in place so someone (without the included 1/2" offset wrench) cannot remove the sensor(s). It takes an extra 10-20 seconds to add air into each tire because of this mechanism, but it's not a big deal. The unit itself comes with adhesive to secure to whatever surface you want which is very helpful so it doesn't move around easily. It constantly charges via the sun. Something to note: I believe the unit turns on when it senses vibration (via closing a door or starting the engine)--but can be turned on (e.g., the display) by clicking any of the buttons. It will then show whatever data was last recorded from your previous trip, BUT once the car moves it takes about 5 seconds of the wheels rolling to update the data (automatically) to the currents stats. Just be aware of that. It doesn't bother me, personally. The description says it has an accuracy of +/- 3 psi. That's an absolute range of 6 psi--a lot of room for error for my liking. Despite that error being apparently similar to other items on desertcart, I have found with my trusted digital tire gauge that this unit reads +/- 1 psi most of the time. That's really good. There's a lot of settings on the device that you can customize to your liking. Other reviews have stated that once it starts beeping (i.e., the tire pressure drops below a set threshold), the beeping will not stop until the pressure is increased. That is FALSE. All you have to do is hit one of the buttons on the top and it stops the beeping. ***Due to the small space you have to tighten/loosen the "security/locking nut", you need the included 1/2" offset wrench (feels like just sheet metal or the type of wrench that comes with furniture). I have an assortment of tools and cannot find a tool that would suffice. Maybe a small open-end 1/2" wrench that is bent or an open-end crowfoot could do it. But a flare nut crowfoot or standard open-end wrench will not do it. I cannot find the included wrench anywhere; so if you lose it, it might not be fun. I WISH THEY WOULD INCLUDE 2 OF THESE WRENCHES IN THE PACKAGE.
Review: Very useful tire pressure gauge - for the spare tire too - About a year and half ago I bought 2 of these TPMS units for 2 of my cars; although they had a different brand name (than Tymate) on them. They have been very useful since they work good and save you from not having to manually check the tire pressures every week or two. This Tymate unit is an updated version of the 2 I already have. They fixed a firmware bug (not an important bug) and put a regular backlight LCD monochrome display in it. The color display in the older units would be slightly affected by summer heat; a few segments would quit working until it cooled off. You could still read it though. With the regular LCD display that shouldn't be a problem. The best part of these units is you can buy a fifth sensor and put it on the spare tire. The head unit will show the pressure in the spare as well as the 4 main tires. The displays alternate. They don't mention that with the Tymate unit but I had a spare sensor from my first 2 units and it works with the Tymate also. The sensors on the main wheels immediately turn on and transmits pressure at 12 MPH but he sensor on the spare takes more time since it doesn't spin. You get a reading from the spare tire sensor often enough though that you can be sure of what pressure is in the tire. Maybe once every 10 miles or so it will get enough bumps to wake it from sleep. To add a sensor for the spare tire press the plus button until it goes into the register sensor mode; then push the plus or minus button to cycle through the different wheel positions until the spare tire icon on the head unit display flashes; then screw the spare sensor onto the spare tire and its ID number will show on the display when the air pressure in the tire turns it on. Then push and hold the middle set button to finish the registration process. That instruction is left out of the manual. The other thing to note with these sensors is it is not at all necessary to use the locknut with the sensors. Just put 'em on without the locknut and snug 'em up. They won't leak or come loose. It's a real pain messing with the locknuts and if you use the locknut on a valve stem of a wheel that has an OEM internal TPMS sensor it will corrode and get stuck. Those TPMS valve stems are aluminum and the brass nut will corrode to them fast from dissimilar metal corrosion. The aluminum threads will get stripped trying to get the locknut loose and ruin the internal TPMS sensor. Ask me how I know that. Even if your car, like my 2013 Prius, has a TPMS from the factory, it will only tell you at least one of your tires is 25 PSI or less. It won't tell you anything more than that, which really isn't very much information. It's a lot better being able to see exactly what is in every tire; including the spare. These things are so accurate; if you're driving a long distance on a sunny day you can tell if you're driving east or west just my looking at the TPMS display. The 2 tires in the sunlight will be a few degrees warmer than the 2 tires in the shade! The only downside (at least with my older 2 units) is the solar panel doesn't put out enough power to keep the battery charged indefinitely. I still have to plug in the USB about once a month to charge the battery to full. Maybe the Tymate won't need that.

## Questions & Answers

**Q: Will they work on a 30 foot travel trailer?**
A: Yes, but I would not buy another Tymate.  We have the four and six monitoring systems.  The four one has a senior that has not worked properly since we bought it.  The company will not respond to my request for help.  Now all of the sensors don’t work.  We had it only 5 months when it quit working.  They advertise a 24/7 help line.  Good luck with that. No phone number to call.  I give these a 0 rating.

**Q: How get in touch with the seller?**
A: It’s not easy to get in touch with them, they don’t respond to emails.

**Q: How about the warranty service？**
A: The warranty period of our products is at least two years. If you encounter any questions about the product during use, please contact us in time  +1(855)-492-9277][EST 9am-5pm Monday through Friday].Support[tymate@afterservice.vip] or contact us directly through Amazon.

**Q: How do I contact the seller when I have a problem during use?**
A: The included instructions provide a phone number. I used it when first setting up and found the support very helpful.

*by P***A on September 22, 2020*

This product helped me avoid getting stranded on my long drive as the real time display allowed me to notice a serious air leak in my rear left tire.. I immediately searched for the nearest Garage and got my tire fixed. -- A real life saver.. Very useful and practical product. -- Prashanth
